DEVICE FOR PREVENTING THE CREPING OF RAILS.

Application led August 23, 1923. Serial No. 658,863.

To vall 'whom it 'may concern.'

Be it known that I, JOHN R. CALDERON, a citizen of the United States,residing at Chicago, in the county of Cook and Sta-te of Illinois, haveinvented certain new and useful Improvements in Devices for Preventingthe Creepin of Rails, of which-the following is a specication.

Thel present invention relates to improvements in devices for preventingthe creeping of rails.

Many devices are known and are being used in connection with railroadrails for preventing the longitudinal creeping thereof. As now known andused, such devices are open to criticism for various reasons, amongwhich may be noted the fact that they afford only a very poor holdingeffect upon the rail and the fact that they are hard to reach forattachment and adjustment.

An object of the present invention is to provide holding means foriirmly gripping a railroad rail.

A further object is to provide means for preventing creeping of arailroad rail, which means is simple to attach and adjust.

A further object is to provide ancanticreeper which may be readilyattached to a railroad rail and by utilizing the resilience of the metalof said rail provide a tight grip upon said rail.

A further object is to provide an anticreeper which combines theadvantages of a tight grip on a railroad rail, readiness ofapplicability and adjustment, sturdiness, and cheapness of manufacture.

A further object is to provide an anti-v creeper which combines theadvantagesl of readiness of applicabilitywith nut locking featureswhereby there is little danger of the anti-creeper becomingloose inservice.

A further object is to provide an anticreeper which serves to firmlygrip a rail with a leverage action and by the same leverage actionperforms nut locking functions.

Further objects will yappear as the description proceeds.

Referring to the drawingsl y Figure 1 is a view of one embodiment of thepresent invention applied to a railroad rail, said rail being shown insection;

Figure 2 is another view of the embodiment of the presentv inventionillustrated in n nut locking features above referred to.

Referring first to Figures 1 and 2, the members 1 and 2 arecomplementary members having the hooked over 'end portions 3 andtrespectively. The hooked over end portions -3 and l are adapted to hookover the opposite' flanges 5 5 of the rail'6. The members 1 and 2'may becomposed of malleable iron, steel, or other tough material capable ofwithstanding the shocks encoun-v tered inrailroad service. The member lis provided with the downwardly extendingl portion 7, which provides aseat 8 for the head 9 of a bolt 10. 'Said bolt 10 normally occupies aposition inclined to the horizontaland to the vertical, ,for *whichAreasonl the seat 8 should be arranged in a corresponding angularposition. The wardly extending portion 7 is provided with a slot 11 forthe reception of thebolt 10, said slot being bounded longitudinally ofthe railroad rail by, the undercut shoulders 12-12the undercutportionsof which form the seat The member 2 is` provided with theoutstanding portion 13,' which is provided v with a hole for thereception of the bolt 10. Any preferred means, such as the lock washer 14 and nut 15, may be provided for holding they bolt 10 and consequentlyholding the `members 1 and 2 in gripping relation to the railroad rail.For the purpose of providing a strong leverage action, the members 1 and2 are formed to provide portions adapted toengage the under side of therail at lines 15-15 relatively distant from the side edges of theflanges ofV down- 16-16 is ad-apted to abut against lthe cross j tie 17.j By reason of the fact that the members 1 and 2 have grippingengagement with the anges of the rail, and by reason of the fact thatthe bolt 10 exerts a leverage action on each of the members 1 and 2about the lines 15-15, the net effect is a very firm gripping engagementbetween the flanges of the rail 6 on the one hand and the members 1 and2 on the other hand. By reason of the fact that the members y1 and 2contact with the bottom of the rail at 'lines spaced materially from theedges thereof, said members 1 and 2 are drawn into such tight engagementwith the rail that slippage is effectually prevented. The angularposition of the bolt 10 accomplishes the further advantage that aworkman may effectually tighten saidrbolt in an expeditious manner. Inpractice a workman may proceed along the track with a socket` wrench andturn downl the nuts on a succession of the bolts 10, working rapidly andwith assurance that a non-slipping engagement with the rail will beaccomplished. By reason of the engagement of the side face 16 with arailroad tie, the structure illustrated in Figures 1 and 2 will preventcreepage in one direction of traiiic, that is tol say-to the right asviewed in Figure 2.

The construction illustrated in Figures 3 and 4 is designed particularlyfor rails in which traiiic is likely to occur in both directions. Theconstruction shown in Figures 3 and 4 is similar to that shown 'inFigures 1 and 2 in most respects. According to the structure shown inFigures 3 and 4, the member 1 has integral therewith a bed. plate 18.Said bed plate 18 extends from one of the sides 16 ot said member 1 in adirection longitudinally of the railroad rail and is provided with apair of shoulders 19-19 spaced apart a distance to receive the base ofthe rail 6. Said bed plate is provided with spike holes 20-20 for thereception of the spikes 21-21, the heads of said spikes 21-21 beingadapted to overlie the flanges 5-5 of the rail 6. Said spikes also serveto prevent movement of the anchor plate 18 longitudinally of the rail.

It will be clear that the construction shown in Figures 3 and 4 providesa practical struct-ure for preventing creeping ot the rails in eitherdirection longitudinally of said rails. rlhe members 1 and 2 cooperatein the manner discussed in connection with Figures 1 and 2 to form atight grip on the rail whereby slippage of the saine is prevented.Movement oi the member 1 and consequently of the rail is prevented byreason of the spikes 21--21 which engage the ties 17.

Referring now to Figures 5 and 6, itwill be apparent that the presentinventionadapts itself readily to nut locking features. As will be clearfrom an inspection of Figures 5 and 6, the outstanding portion 13 isposition the bolt 10 will have been bent materially at its threadedportion. The threads on the concave side ofV the bent bolt 10 will becompressed and the threads on the convex side of the bent bolt l() willbe spread. By reason of this action the nut 15 will be eifectuallyprevented from backing oil'7 though said nut may be removed by a workmanprovided with a proper tool.

The lock washer 14 may or may vnot be Y used, as'desired, in theconstruction shown in Figures 5 and 6. It will be clear that the nutlocking features shown in Figures 5` and 6 are applicable tothestructures shown in Figures 1 to 4.

Though certain practical embodiments of the invention have beenillustrated, it will be clear that many modiiications are possible andwill occur to those skilled in the art. It is intended in this patent tocover all such modications which fall within the scope of the inventionas defined by the Vappended claims.
